We are conﬁdent that you will enjoy many years of listening pleasure from it. Developed as part of our on-going research and development regime, including extensive listening tests, we have incorporated many subtle tweaks and improvements to our circuits, components and layouts in the pursuit of our passion for sound quality. Speciﬁcally, these models use new output transistors, a new high-quality Alps volume pot, new polypropylene signal capacitors, gold-plated speaker outputs, custom- made electrolytic capacitors in critical positions and several new circuit tweaks. These models are amongst the ﬁrst to feature a new casework design with a thicker braced front panel, more rigid wrap-over lid assembly and dual-layer damped feet, all of which contribute to better resonance control. A new version of our proprietary CAP5 system has been developed to allow a greater dynamic envelope to the protection scheme, offering a more dynamic real-life performance. Also featured is an environmentally friendly low power (<1W) standby circuit. This circuit completely powers down the ampliﬁer circuits in Standby mode yet is itself totally isolated when the ampliﬁer is on, thus having no effect on sound quality. Both the 550A and 650A have fully buffered input circuits for low crosstalk and improved stereo imaging, driving a completely discrete bipolar transistor-based ampliﬁer and all powered from a custom audiophile-grade toroidal transformer. A new MP3/Portable Media Player input has been ﬁtted to the front panel for convenience, and the supplied remote can control the ampliﬁer, any of our matching CD players and basic iPod functionality. The 650A differs from the 550A by having separate transformer secondaries for left and right channels, twin rectiﬁers and separate PSUs for dual-mono operation of the left and right power ampliﬁers. An even larger heatsink and transformer are also employed which allows for a greater power output of 75wpc (compared to 60wpc for the 550A). Your ampliﬁer can only be as good as the system it is connected to. Please do not compromise on your source equipment, speakers or cabling. Naturally, we particularly recommend models from the Cambridge Audio Azur range, which have been designed to the same exacting standards as our ampliﬁers. Your dealer can also supply excellent quality Cambridge Audio interconnects to ensure your system realises its full potential. Thank you for taking the time to read this manual; we recommend you keep it for future reference.

Install in accordance with the manufacturer's instructions. 8. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including other ampliﬁers) that produce heat. 9. Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades with one wider than the other. A grounding-type plug has two blades and a third grounding prong. The wide blade or the third prong are provided for your safety. If the provided plug does not ﬁt into your outlet, consult an electrician for replacement of the obsolete outlet. 10. Protect the power cord from being walked on or pinched, particularly at plugs, convenience receptacles and the point where they exit from the apparatus. 11. Only use attachments/accessories speciﬁed by the manufacturer. 12. Use with only the cart, stand, tripod, bracket, or table speciﬁed by the manufacturer, or sold with the apparatus. When a cart is used, use caution when moving the cart/ apparatus combination to avoid injury from tip-over. 13. Unplug this apparatus during lightning storms or when unused for long periods of time. 14. Refer all servicing to qualiﬁed service personnel. Servicing is required when the apparatus has been damaged in any way, such as the power-supply cord or plug having been damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped. WARNING – To reduce the risk of ﬁre or electric shock, do not expose this unit to rain or moisture. – Batteries (battery pack or batteries installed) shall not be exposed to excessive heat such as sunshine, ﬁre or the like. The unit is of Class 1 construction and must be connected to a mains socket outlet with a protective earthing connection. The unit must be installed in a manner that makes disconnection of the mains plug from the mains socket outlet (or appliance connector from the rear of the unit) possible. Where the mains plug is used as the disconnect device, the disconnect device shall remain readily operable. Only use the mains cord supplied with this unit. Please ensure there is ample ventilation. We recommend that you do not place the unit in an enclosed space; if you wish to place the unit on a shelf, use the top shelf to allow maximum ventilation. Do not put any objects on top of this unit.
